Classic version of f.lux?

I like for the f.lux settings to follow a certain pattern which involves going below 1900K at times. In the old version, I used to be able to achieve that pattern by seting where I lived (e.g. moving "position" east/west and north/south until the sun followed the pattern I needed).

In the current version, the number of hours that f.lux can go below 1900K is (more or less) fixed. Furthermore, the EULA forbids us from downloading an older version to replace this "updated" version, except from your website. How can I get permission to install the older version of f.lux on my computer?
Thanks in advance.
